ratus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification- My'invention relates to improvements in train-ventilating a paratus, and while more especially intende for use in ventilating rallway cars. it may of course be. employed forthe ventilation of any vehicles or other moving structure where the necessity for pure air is a desideratum.

My improved construction as illustrated in the drawings is more especially adapted for use in ventilating individual cars. In other words, its successful use does not necessitate that there shall be a number of cars in the train, since a train having but one car may be as successfully ventilated aswhere a number of cars are connected. 4

My special object'is to relieve the air of the dirt,'cmde'rs, &c., with which under ordinary circumstances the air is laden when it enters .the car s. Y

My improved apparatus includes means for cooling the air as well as means for filtersu stances are removed.

in it, whereby the dust and other foreign Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference beingfimade to the accompanymg drawings, in w ch is illustrated an embodiment thereof. 7

In the drawings, Figure 1 is a vertical longitudinal section taken through a railwaycar equipped with'my improvements. Fig, 2 is a detail view, partly in section, illustrating the ap aratus connected with the top of the car. ig. 3 is a sectional view of the filter-tank, the filtering-bag being shown partly in elevation.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a railway-car to the top of which is secured a conduit .6,

which is passed back and forth a number of detail in Fig. 2. The pi e connected with the sma er extremity of the times in order to cause the airrto, travel a con The pi e 6 should be wrapped with between the funnel and'the pipe is shownain member 8 directly funnel, is provided with 'a -bearing member 9, having a circular grooveforming a half ballrace for bearmg-balls 10, the other half-race being formed in the member-12 of the conduit 6. The two parts'9 and'12 are retained in operative relation by a coupling-sleeve 13.

The larger extremity of the funnel is pro-- vided w th a screen, as shown at 14, whereby the la'rger or coarser particles are prevented from entering the funnel.

The extremity of the pi e 6. opposite 'that connected with the funne s curved downwardly, as shown at 16, andis provided with a vertical member 17, passing-through the car and communicating at its ower extremity with a conduit member 1 8, which'after passing underneathf the car a certain distance passes upwardly through the bottom of the car and enters a filter-tank 19 located in the car, and infiwhich is located a iilter-bag 32, into which the air is delivered from the open extremity of the conduit 18. To the upper extremity of the filter-tank 19 is connected an elbow-shaped air-delivery conduit 20, through which the filtered air asses from the filter-tank into the car. is elbowshaped structure is provided with a slidevalve 21, whereby the passage of air therethrough into the car may be controlled or entirely out off, as may be desired. At the 11pper part of the filter-tank is also located a coil ICO of pipe 22," through which steam or other heating or tempering agent may be passed I for the pur ose of regulating the temperature of the. air before it escapes from the filtertank into the car.

The lower extremity of the pipe 17 extends below the bottom of the car and is closed by a lever-like valve 25, fulcrumed at 26. To one arm of this device is attached a flexible relieve the stand pipe17 from the accumula .anydirt and .cinders that it in case the valve 21.

zescmpe of theiair fr the top \of: the filterbe used todevice 27, as a cordor chain, whose upper extremity is provided with a ring 28, adapted to engage a pin 29, whereby the operating chain or cord is in convenient poslti'on for use. This valve 25 is held normally closed by a weight 30, located between thef ulcrum 26 and the outer extremity oftheleverdike device. The airv which passes through the I pipe 17 may deposit foreign matter therein.

his foreign substance will naturally drop downwardly in the pipe and engage the valve 25 and when ofsuficient weight will open the said valve automatically and allow the material to escape, or the lever-like valve may be opened'bypulling upwardly on the flexible device 2.7 whenever it is desired to tion of foreignsubstance.

I From the foregoing description the use and voperation of my improved apparatus will be meadily understood. Assuming that a car is equipped the apparatus, the larger extnemity of, the will :be held in the ection firom which the wind. is blowing b viriltue of the vane connected therewith, as heretotore explained. As the. wind changes the direction of the mouth of" the funnel will change by virtue of its swiveled connection with the conduit 16, mounted on top of the car. The air atter entering the funnel is driven by the'neoessary pressure through the conduit .6, wherein the is cooled to a .con-' siderable extent.
